STORAGEBATTERY LOCOMOTIVE.

Specification of Letters Patent. Patnted Apr.` 25, 1922.

Application led August 9, 1920. Serial No. 402,413.

land, in the county ot Cuyahoga and Statev ot Ohio, have invented certain new and useful improvements in Storage-Battery Locomotives, ot which the following is a specification.

This linvention relates to storage battery locomotives and more particularly to the mounting or support for the battery boxes thereof. ,y

The object ot' the invention is vto provide which enables it to be more readily handled eitherinplacing it upon or removing it from the car or to expose the driving motors or `other mechanism ot the locomotive for re-v pairs Aor adjustment.

In the drawings, Fig. 1 represents a side view, partly broken away and in section on theiline 1 1, Fig. 2, representing one embodiment of the invention; Fig. 2 is a detail section of* one side of the car on the line 2--2, Fig. 1; Fig. 3 is a rear view showing the locking device; F ige is a plan view of the movable track; Fig. 5 is a side view showing another, 'form of the invention; Fig. 6 is a rear elevation; Fig. 7 is a side view of the'rear ot the car showing the tracks extended; and Fig. 5% is a plan view illustrating still another form of the invention.

In storage battery locomotives of this type.

it is frequently necessary to move the battery box or boxes while the car is in the mine, `tor example, when because of a taulty brush or the like the motor stops, in which case a simple repair made on the spot will prevent taking the locomotive outside of the mine or toa suitable room or place where there is head room enough `for a crane to lift the box. Moreover the limited width of manyy mine passages does not permit turning*` Referring to Fig. 1, 1 represents the locomotive frame supported by wheels 2 resting on the track-s 3. The dotted circles 4 represent `the two driving motors which are in y their customary positions in locomotives-of this class. 5 represents the battery box which is ot any suitabie Yform for supporting the proper numberI of battery cells. The

ft'ront end ot the locomotive is at the right,

Fig. 1.

Box 5 is suitably constructed and mounted for sliding movement upon the locomotive trame, in,A a manner to expose the driving motors. rlhis may be accomplished inV several ways. In F l the boxis provided Y Vtoward its 'trout end and on each side with a mounting or support vt'or the battery boxV one or more rollers 6 which travel on tiXed tracks, suoli as angle irons 7, secured to the lside frame members 8. it is also provided rearwardly of the rollers 6, such asl near the bos center, with depending brackets'9 vcarrying rollers 10 which rest upon movable track members 11. These *track members are inthe 'form of bars connected at the rear oit the locomotive by a cross -piece 12 and indeed. the parts 11 and 12 may be'integral with each other. Tracks 11 in turn slide upon rollers 13 journalled upon studs in the 'frame 1. Theyr are preferably Vprovided with suitable means such vas the blocks or abutments 14, which engage the rear wall of the frame to limit their rearward movement and may also be provided Vwith brackets 15 adapted to be engaged by the brackets 9 so that when the box is moved rearwardly from normal position it will pull out or extend the movable tracks with it. This arrangement provides a {iXed track upon the locomotive traine and a rearwardly extensible track so that the battery box may be easily rolled rearwardly practically its own length to eX- pose both motors and all other working parts ot' the car. Tracks 11 may also carry rollers 14a which'lie under the tracks 7 and prevent the tracks 11 from tilting down when withdrawn.

The movable track :trame 11, 12 may also carry a Ueshaped leg member 16 the two arms of which are pivoted at 17 to the movable track members. This leg member normally folds up within the movable track and is concealed with it in the frame, but when the rearward movement occurs it drops down to the position shown in dotted lines Fig. 1, when it rests upon the rails 3 and supports the box in its new position.

The locomotive may also be provided with suitable means for locking the box in its normal forward position to yprevent it 'from accidentally sliding rearwardly and possibly injuring a person sitting or standing at the rear end of the locomotive. The drawings show for this purpose two pivoted latches 18 carried by the box and normally hanging with their lower ends in front of a cross bar 19 of the trame, but which can be turned to the dotted line position, Fig. 3 yto release vthe box when desired.

Figs. 5, G and 7 show another arrangement in which the battery is divided and is carried in two separate boxes 5a.y 5b, each of which has rollers 20 travelling upon fixed tracks 2l of the trame. frame are located two cantilever track arms 22 pivoted upon vertical axes 23 at the sides of the frame. The normal position of these arms is shown in Fig. 5 but when desired :they may be turned out Aas shown in Fig. 7

and form extensions oit' the tracks 2l. To

expose the rear motor the box 5a alone is moved rearwardly, while by moving both boxes 5, 5b rearwardly the forward motor is exposed. 30 are limiting stops upon the Similar track arms 22C, in another form vof @the invention may be pivoted both upon the same side of the car', as shown in Fig. 8, forming track extensions to be extended laterally to a portable track trame 24C uponthe Verally'either to gain access `to the motors or to 'enable battery boxes to be changed by rolling another Vbox upon the car from a 'room at the other side of the car across a At the rear of theduplicate pair of track arms at thev other side of the car.

lNhat we claim is:

l. A storage battery locomotive comprising a frame, va battery box, and means carried by said trame and extensible through a horizontal Yplane for supporting and guiding said box for bodily movement out of its normal position-on the locomotive.

2. .A storage battery locomotive, comprising a trame, a battery box thereon, tracks upon said trame and extensible through a horizontal trame, and rollers carried by the box and traveling on said tracks.

3. ik storage battery loc'omotii'f'e, comprising a trame', a battery box thereon, tracks upon saidframe, and rollers carried by the box and traveling on said tracks, portions o'l said tacks being` extensible through a horizontal plane beyond the locomotive body.

Il. A storage battery locomotive, comprising a frame, a battery box thereon, tracks upon saidfliraine.r and rollers caiiied by the 'box and traveling on said-tracks, said tracks including portions which may be moved through a lhorizontal plane to either of two positions; in one of which they are Withdrawn within, and in the other of which signatures.
